CHEMICAL-FEEDING DEVICE.

To all whom it may concern:

Beit known that I, JOHN E. CAPs, citizen of the United States, `residing at lilmetie, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chemical-Feeding Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

rlhis invention relates to a novel construction in a device `for injecting a measured quantity of chemicals for softening water into water flowing through a pipe, the object being to provide a simple and etlicient device of this character which will permit variation at will of the quantityof'chemicals introduced, and consists in the features of construction and combinations of parts hereinafter fully described and claimed.

` In the accompanying drawings illustrating my invention: Figure -1- is a view partly in vertical section and partly in elevation of a device constructed in accordance with my invention. Fig. -2- is a vertical section of the same on the line l2--2 of Fig. -l-.

My present invention is designed particularlyv for use in connection with the apparatus for heating water forming subject of the application of C. A. Cartwright for Letters Patent Serial No. 488,027, tiled April 5, 1909, and has for its particular object to:provde means whereby water softening chemical may be introduced into all of the Water en tering vvthe system from the service pipe. It will be understood that its use is not limited to this particular purpose or in connection with this particular apparatus.

The object of the invention is to provide means whereby a measured quantity of Water softening chemical is introduced into a measured volume of water, the latter automatically controlling the feed.

ln the drawings A indicates a source of supply of water under pressure from which water passes to the pipe B through the pas sage C in my device. My said device couv prises a suitable frame which includes a cylindrical chamber D in which a water wheel E is revolublymounted, the shaft F of the latter projecting therefrom and carrying a spur pinion G which meshes with a spur gear H suitably rotatably mounted on the frame. The blades of the said water wheel speciacauoaof Leiters raient. i Application tiled July 23, 1909. Serial No. 509,214.

below and integral with said valve.

E project into the passage C which -is disposed tangential with and 'communicates with said cylindrical casing D, the iiowing water serving to rotate said water wheel in a well-known manner.

Ilxtending transversely to the passage C is a pump cylinder l which communicates at one end with said passage C between the ends of the latter. The connection between the-pump and said passage C is controlled by a valve J normally held on its seat by means of a spring K bearing at one end thereon and at its other end against the `lower vend of .a guide member L disposed in a. pipe M integral with and extending transversely to the passage C in axial alinement withrthe pump cylinder I. Said guide member L is integral with the cap N closing said pipe M and is provided with a central guide recess O in which the upper end of the stem P of said valve. J is received, said valve being guided partly by the engagement of its stem with the wall of the opening O and partly by the spokes or flanges Q disposed Communicating with said pump between its ends is a pipe R having a check valve S disposed therein and which is connected with a source of supply of chemicals in solution. The piston T of said cylinder is of the trunk type and is cnnected by 'means of the pitman U with the segmentally slotted segmental arm V of a lever' pivotally mounted between its ends on a part of the frame of the device, said, lever being connected at its other end with'the pitman W, the latter being connected with the crank pin X carried by said spur gear H, said lever being oscillated thereby. Mounted onthe free end of the segmental arm of said lever is a. swivel nut `Y through which a set screw Z passes, the

latter being revolubly connected at its inner end with a swiveled member 27 disposed on the head 28 at the lower end of said pitman U. On said segmental arm V is a graduated scale the graduations of which are Drefer ably numbered to indicate the different quantities of chemical delivered upon each stroke of the pistou when the said head 28 bf the pitinan is disposed to register with `said respective graduations.

The operation of the device is very simple and easilv understood from the foregoing description. :lt will be obvious that water passing through the passage C will rotate the water wheel E and the latter in turn will rotate the spur `rear ll and this bv its eolineetion with the lever\\'illoseillat.e`the latter y The drawings illustrate a suitable einbodilnent ot' my invention but no attempt has therein been made to adhere to proper relative proportions of the parts, itI being understood, of course, that these may be changed and varied without departing' trom the spirit of the invention. i

I claim as my invention:`

l. In apparatus of the kind specified, a water supply pipe equipped with a perpendieularly disposed cylindrical arm constituting a pump cylinder', a check-Valve eontrolled inlet for water-softening chemical between the ends of said ,punip-eylind er, a piston in the latter, a valve controlling the comnuinieation of said Cylinder with said water supply pipe, a spring maintainiinr the same normally closed, a vater motor aetnated Lby the passage of water through said pipe, and gearing between said motor and said piston to reciprocate the latter.

ln apparatus of the kind specified, a water supply pipe equipped with a perpendieularly disposed eylindriealarm consti tuting a pump Cylinder', a cheek-valve Con trolled inlet for water-softening chemical between the ends of said pump-cylinder, a piston in the latter, a valve controlling the eonununieation of said cylinder with `said water supply pipe, a springmaintaining the same normally closed, a water motor aetu ated by the passage of water through said pipe, gearing between said motor and said piston to reeiproeate the latter, and means interposed in said connection for varying the stroke of said piston. o i

In testimony whereotl I have signed my name in presence of two subseribii'ig' witnesses.
